If you ignore the fact that much of the planet is occupied by agriculture, then you would be correct. Most of the land on this planet is being occupied by humans. The few places that aren't occupied are either locations like the Amazon rain forest, which is being threatened every year, or places like the Sahara desert, which very few species can survive in and is very undesirable.

29% of Earth is land mass. Of that 29% humans occupy less than 1% of that area. Of the remaining 28% about 40% is pure wilderness. 14% is true desert and 15% has desert like characteristics. 9% is Antarctica. Most of the remaining 22% are agricultural areas.
